I've been learning HTML and CSS for some weeks now and I start feeling fortable with those. However I'm trying to learn JavaScript too.
I've been working on a button in HTML and CSS, you can view the demo of the button here.
I want to make the dropdown menu visible when you click the button and also if you click the button again the dropdown menu disappears.
Is there any simple or understandable way for creating a function which does this in JavaScript?
Here is the code I have:
HTML:
<div id="language-wrapper">
<a class="language-icon fr" href="#" alt="choose-your-language">Language</a>
<div id="language-dropdown">
<h3>Choose your language</h3>
<a class="language-links" href="#">Chinese</a>
<a class="language-links" href="#">Danish</a>
<a class="language-links" href="#">Deutsch</a>
<a class="language-links" href="#">English</a>
<a class="language-links" href="#">Espanol</a>
<a class="language-links" href="#">Filipino</a>
<a class="language-links" href="#">Hindu</a>
<a class="language-links" href="#">Italiano</a>
<a class="language-links" href="#">Norsk</a>
<a class="language-links" href="#">Nederlands</a>
<a class="language-links" href="#">Polski</a>
<a class="language-links" href="#">Portugues</a>
<a class="language-links" href="#">Svenska</a>
<a class="language-links" href="#">Suomi</a>
<a class="language-links" href="#">Turkce</a>
<a class="language-links" href="#">Urdu</a>
<p>Do you speak multiple languages or can't find your language? <font color="#d13030">Help us translate!</font><p>
</div> <!-- end of language-dropdown class -->
</div> <!-- end of language-wrapper -->
CSS:
#language-wrapper { display: inline-block; }
#language-wrapper:hover #language-dropdown { opacity: 1; display: block; }
.language-icon {

Reset to default 2it can be a basic toggle display function on onclik event:
function toggle(el) {
var tag=document.getElementById(el);
tag.style.display = tag.style.display === 'block' ? 'none' : 'block';
// set as defaut oposite defaut active value in document
// here defaut is set to block cause it is none in CSS
}
<a class="language-icon fr" href="#" alt="choose-your-language" onclick="toggle('language-dropdown');">Language</a>
test here : http://codepen.io/anon/pen/cHIrd/
note:
opacity:0; removed from your initial CSS
Better practice is to toggle class not style values :)
and maybe to set onclick event via javScript.
return false can be added to avoid link to href .
<a class="language-icon fr" href="#" alt="choose-your-language" onclick="toggle('language-dropdown');return false;">Language</a>
The Html
<button id="clickme">Clickme</button>
<h1 id="Another">Menu</h1>
The JavaScript:
document.getElementById("clickme").onclick=function(){
var el = document.getElementById('Another');
if (el.style.display == '') {
el.style.display = 'none';
alert("hide");
}else{
el.style.display = '';
alert("show");
}
};
Here is a sample
